Meditation programs for adults with type 2 diabetes mellitus: A protocol for a systematic review and meta-analysis

Type 2 diabetes mellitus is intimately linked to chronic stress. Meditation programs belong to mind-body therapies, which could benefit patients’ disease management. Though some clinical trials have proved that meditation programs have the ability to improve level of blood glucose quality of life, body mass index and blood indexes related to metabolism in individuals with type 2 diabetes mellitus, the efficacy of meditation programs needs further confirmation. Thus we will conduct this systematic evaluation and meta-analysis to summarize and analyze all the results included to obtain reliable evidence. METHODS: We will search several English and Chinese databases for relevant clinical trials published up to July 2021, and randomized controlled trials or controlled trials among adults with type 2 diabetes mellitus are included. Two reviewers will extract data and assess the quality of included studies independently. The main outcomes of this research are glycosylated hemoglobin level and fasting blood glucose level. The secondary outcomes are high-density lipoprotein, low-density lipoprotein, body mass index, remission of depression and anxiety, and quality of life. Stata v.14.0 and Review Manager V5.3 will be used to synthesize and analyze all data included. RESULTS: Grading of Recommendations Assessment, Development, and Evaluation will be used to evaluate the quality of the assessments. Our study will be disseminated through publications in peer-reviewed journals. CONCLUSION: This systematic review is the first to analyze the efficacy of different types of meditation for type 2 diabetes mellitus, which could provide evidence for the use of mediation programs as non-drug approaches.
